What the research says
2 studies reviewedSupporting (2)
Randomized Phase 2b Dose-Escalation Trial of Stem Cell Therapy with Laromestrocel for Aging Frailty
Randomized Controlled TrialHuman2026
This study gave older adults a stem cell treatment and found they could walk much farther after nine months, and a key blood marker of aging improved too. That means the treatment helped reverse some signs of aging in their bodies.
Randomized Controlled TrialHuman2025
This study gave older adults with early memory problems a stem cell treatment and found their brains shrank much slower than those who didn’t get the treatment. Slower brain shrinkage means the treatment helped fight signs of aging in the brain.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Stem cells release a protein that blocks an enzyme from cutting a key receptor on blood vessel walls. This keeps the receptor active, which strengthens blood vessels, improves blood flow to muscles and the brain, and reduces inflammation. As a result, tissues like muscle and brain age more slowly, leading to better movement and slower shrinkage of brain tissue.
